IMPLICATION OF BROADBAND RADIO ACCESS TO UMTS

摘要

The Universal Mobile Telecommunication System (UMTS) - third mobile communication standard developed by ETSI was planned to provide bit rates up to 2 Mbit/s for Indoor coverage (till 10 meters, for office and home environments) for low mobility user end up to 384 kbit/s for outdoor coverege (till 20 km, for suburban and rural areas) for high mobllity users. The existing and future Internet and telecommunication services have demands for higher bit rates and wider bands than UMTS as 3rd generation technology can provide. There are new projects in ETSI and around the world, which research and develop standards for fixed and cordless broadband radio accesses.
